A smooth base on these metric nuts provides more contact with the mating surface than weld nuts with projections

Projections on the base concentrate the weld and provide room for heat to dissipate.

These steel nuts have a short collar to fit in low-clearance areas.

Add strong threads to material that you can't drill or that's too thin to grip a threaded insert. These nuts are ideal for brittle plastics or tough composites, such as acrylic or carbon fiber.

Fit these nuts into channels, corners, and other tight spaces to add strong threads without drilling a hole. They’re ideal for material that’s too thin or too hard and brittle to drill, such as acrylic and carbon fiber.

Adhere or mold these nuts onto a surface without gunking up the threads—the closed end blocks out adhesive, resin, and debris. Made of 316 stainless steel, they resist corrosion from salt water and harsh chemicals.
